Wave 10 Part 1 Start Month?

Has anyone seen anything about what month the first part of wave 10 is going to start? April should see the release of the Starlight Theater and Space Sentry robots but I have not heard about the X-01 power armor set. So is that also coming in April or will it be released all on its lonesome in May? Depending on that will probably set if Wave 10 is starting in May or June.
